Apache Commons
Apache Commons is a collection of reusable Java components designed to simplify common programming tasks. It provides libraries for various functionalities, such as data manipulation, file handling, and configuration management, making it easier for developers to implement standard features without reinventing the wheel.
The project is part of the larger Apache Software Foundation, which supports open-source software development. Each component in Apache Commons is modular, allowing developers to use only the parts they need, thus promoting efficiency and reducing code complexity in Java applications.
